  • Fully threaded pointed tip allows for easy starting and smooth driving, enhancing assembly speed and accuracy.

Professional Applications & Engineering Value

These No. 0 Phillips flat head tapping screws are engineered for demanding sheet metal applications, where material integrity and corrosion resistance are critical. The 18-8 stainless steel composition provides excellent durability against moisture and chemicals, extending service life in industrial settings. The thread forming (AB type) design eliminates the need for separate tapping operations, reducing labor costs and preventing thread stripping in thin-gauge metals. With a right-hand thread and pointed tip, these screws ensure quick alignment and secure fastening in assemblies up to 0.025" thickness, making them ideal for electronics enclosures, HVAC systems, and automotive panels where reliable, corrosion-resistant fastening is essential.

Specification Summary & Compliance

This product features a thread diameter of 0.06" with 48 TPI precision and standard inch measurements for consistent performance. It complies with RoHS 3 (2015/863/EU) regulations, ensuring it is free from hazardous substances. The screw is designed with a flat head and Phillips drive (No. 0) for secure installation and is fully threaded for maximum holding power in applicable materials.
